Abstract

In order to solve the problem that buffer cells set among different cell clusters using same or adjacent carriers and operating in time division duplex mode wireless communication networks to attenuate inter-cluster interference can not obtain communication service, thereby causing mass waste of communication capacity, the present invention provides the following steps: the base station of the buffer cell acquires multiple sets of resource-allocation information that correspond with the multiple adjacent cell clusters respectively; then, based on said multiple resource allocation information sets, the uplink and downlink time-slot configuration is confirmed for the cells governed by this base station, so as to ensure that no inter-cluster interference is produced between the buffer cell and the multiple cell clusters. Correspondingly, the base stations of the cell clusters adjoining the buffer cell transmit the resource allocation information of their own cell clusters to the base station of the buffer cell. Based on the present invention, the time slots of the buffer region are configured as uplink and downlink time slots, thus providing communication service to the buffer region, improving user experience, and increasing transmission capacity in the buffer region.

Description

Method and apparatus for the buffer configuration time slot between a plurality of cell clusters

Technical field

The present invention relates to cordless communication network, relate in particular to the method and apparatus of configuration uplink and downlink time resource in the tdd systems of cordless communication network.

Background technology

Time division duplex (TDD) is a kind of Modern Communication System duplex mode commonly used, in the mobile communication system of TDD mode, receive and send the different time-gap of the same frequency carrier of use as the carrying of channel, guarantee to receive and the separating of transmitting channel with the time, can not conflict between namely guaranteeing to receive and sending.Further, each receiver uses different receiving slots, receives corresponding transmitter at the signal of the different time-gap transmission of correspondence, has guaranteed between each receiver, and can not produce conflict between each transmitter.

In the TDD system, same carrier frequency can produce the different scene of uplink and downlink time slot configuration, for example:

A. in the heterogeneous networks zone of an operator inside because the distribution situation of uplink and downlink business is different, think that zones of different has the configuration of different uplink and downlink resources, also be the ratio of uplink and downlink time slot.For example, in the commercial affairs zone that office building is relatively concentrated, consider that voice service is more, the uplink and downlink business remains basically stable, and is basic identical in this regional uplink and downlink configuration; In the residential area, consider that the demand of general resident's downloading data in this zone is larger, and uploading data is less, therefore more for the descending time slot configuration, the ascending time slot configuration is less.

B. similar, different operators also the problems referred to above can occur in zones of different.Also namely, different operators is runed respectively network separately, takes different strategies, thereby different to the uplink and downlink configuration of the system resource of each automatic network.

Meanwhile, because the operator can only obtain issuing fixed a small amount of frequency resource usually, therefore limit by number of frequencies, the network area of these operator inside may shared on a small quantity, even an identical carrier frequency (for example, being the carrier frequency of 700MHz); Simultaneously, also may share same carrier frequency resource between the different operators.In this case, when the adjacent different districts that uses same carrier frequency has different uplink and downlink time slot configuration, disturb between can producing bunch.Namely use a slot transmission up-link information when one of them residential quarter, and use another neighbor cell of different uplink and downlink timeslot configurations to use same slot transmission downlink information, may have interference between two residential quarters so.

Concrete, in synchronization or same time period, when the portable terminal that is positioned at a residential quarter receives information, and another portable terminal that is positioned at neighbor cell sends information in same carrier, and these two portable terminals all are positioned at cell edge and are separated by when nearer, the signal that the portable terminal of transmission upward signal sends may to arriving at another portable terminal place that receives downstream signal with same carrier, produce interference to its downstream signal that receives same carrier.

In addition, between two adjacent carrier frequency, consider adjacent frequently leakage, namely the energy of a carrier frequency not necessarily concentrates on centre frequency, the energy of this carrier frequency can be leaked to adjacent carrier frequency, therefore disturb between using the residential quarter of this frequency can and use to produce between the neighbor cell of adjacent carrier frequency bunch, for example, a carrier frequency is 405MHz, another carrier frequency is 400MHz, in synchronization or same time period, when being positioned at the portable terminal reception information that carrier frequency is the residential quarter of 400MHz, be that another portable terminal of the neighbor cell of 405MHz sends information in same carrier and be positioned at carrier frequency, and these two portable terminals all are positioned at cell edge and are separated by when nearer, sending signal that the portable terminal of upward signal sends with the 405MHz carrier frequency may be to arriving at another portable terminal place that receives downstream signal with adjacent carrier frequency, its downstream signal that receives adjacent carrier frequency is produced disturb.

In the prior art, in order to address the above problem, in the juncture area between the cell cluster of the different uplink and downlink time slot configuration of two or more uses the buffer area is set, this buffer area does not arrange the base station.Owing to cover without the base station, then the time slot on this buffer area is reservation, also namely sacrificed the time slot in the buffer area, with the decay through the buffer area of the upward signal that guarantees a portable terminal in the residential quarter, can not cause interference to the downstream signal of residential quarter on same time slot of buffer area another side.

Obviously, because this buffer area does not arrange the base station in the prior art, thereby can bring following shortcoming:

1. the user in the buffer area can't obtain communication service, and the user experiences very poor;

2. the transmission capacity in the buffer area is zero, and when the buffer area is larger, can cause larger traffic capacity loss.

The buffer area of buffer cells 1 between the first cell cluster CC1 and the second cell cluster CC2, buffer cells 1 is by base station A jurisdiction, base station A distributes relevant information according to the up-downgoing resource of the first cell cluster CC1 and the second cell cluster CC2, for buffer cells 1 is carried out the configuration of up-downgoing resource.Buffer cells 1 can be adjacent with one or more bunches bunch edge cell, in Fig. 1 for convenience of explanation, only bunch edge cell 3 and 5 of bunch edge cell 2 of display buffer residential quarter 1 and the first cell cluster CC1 and the 4 and second cell cluster CC2 is adjacent, further, because the uplink-downlink configuration situation of all residential quarters among the first cell cluster CC1 is consistent, and the uplink-downlink configuration situation of all residential quarters among the second cell cluster CC2 is consistent, below, for convenience of explanation, bunch edge cell 2 in the first cell cluster CC1 is as example, represent the first cell cluster CC1 and describe, bunch edge cell 3 in the second cell cluster CC2 is as example, and the second cell cluster CC2 describes.

In the reality, in one case, the first cell cluster CC1 can be configured based on same standard by identical operator with the second cell cluster CC2, and each time slot complete matching of correspondence in every frame of the first cell cluster CC1 and the second cell cluster CC2, but the first cell cluster CC1 is incomplete same with the uplink and downlink configuration mode of the corresponding time slot of the second cell cluster CC2; In another case, the first cell cluster CC1 can be configured by different operators with the second cell cluster CC2, therefore, may adopt different network standards.For example, the first cell cluster CC1 adopts the TDD network based on Wimax, and the second cell cluster CC2 adopts the TDD network based on LTE, and therefore each time slot in the frame of the first cell cluster CC 1 and the second cell cluster CC2 not exclusively aligns.Below, the present invention will be described for above-mentioned the first situation first for we.

Describe as an example of Fig. 2 example, Fig. 2 is the schematic diagram according to the uplink and downlink configuration of the time resource of bunch edge cell 2 of a specific embodiment of the present invention and bunch edge cell 3.Time slot in each corresponding frame of the first cell cluster CC1 (bunch edge cell 2) and the second cell cluster CC2 (bunch edge cell 3) aligns herein.At this, time resource refers to time slot, but those skilled in the art will be understood that according to following description the time resource of other types also should be able to be applicable to the present invention.

The below comprises seven time slots take a frame and describes as example, and the number of the time slot that comprises in the frame is determined by the frame format of defined in the standard of place network.For example; in the TDD of LTE network; the frame of a 10ms comprises the subframe of two 5ms; each subframe comprises 7 time slots; 7 time slots of the buffer cells 1 among Fig. 2 are respectively TS0 to TS6; for convenience of explanation, omitted protection interval between the adjacent time-slots etc. herein, the uplink and downlink configuration only has been shown.Each time slot corresponding with each time slot TS0-TS6 of buffer cells 1 is respectively TS0 '-TS6 ' in one frame of bunch edge cell 2, and each corresponding with buffer cells 1 each time slot TS0-TS6 time slot is respectively TS0 in the frame of bunch edge cell 2 "-TS6 ", wherein, corresponding time slot is fully overlapping on time shaft.If represent descending time slot with D, U represents ascending time slot, as shown in Figure 2, as example, each time slot TS0 '-TS6 ' in one frame of bunch edge cell 2 be D D D U U D U, each time slot TS0 in one frame of bunch edge cell 3 "-TS6 " be D D U U D U U, and the uplink and downlink timeslot in bunch edge cell 2 and 3 remained unchanged in a period of time.

The first embodiment

Fig. 3 is used to the method flow diagram of buffer cells configuration uplink and downlink time slot for the base station A in the buffer cells of cordless communication network according to a specific embodiment of the present invention.

Referring to Fig. 3 and in conjunction with Fig. 1 and Fig. 2 first embodiment of the invention is described, wherein, the first embodiment comprises for the resource distribution relevant information that base station A obtains: be respectively applied to indicate the situation of the uplink and downlink time slot configuration information of each self-configuring among the first cell cluster CC1 and the second cell cluster CC2 to describe.

At first, in step S10, base station A obtains the first cell cluster CC1 and resource corresponding to the second cell cluster CC2 difference distributed relevant information, and wherein, this resource allocation information comprises respectively the configuration information of the uplink and downlink time slot of the first cell cluster CC1 and the second cell cluster CC2.For a cell cluster, the uplink and downlink time slot of all residential quarters in this cell cluster can be pre-configured by operator or base station at the network configuration initial stage at this place, residential quarter, also can be dynamically to be adjusted by the base station according to network demand, also be, giving certain concrete portable terminal with a time slot allocation is dynamically to be determined by the base station, and the communication mode of the uplink and downlink of this time slot is pre-configured by the base station, and remains unchanged within certain cycle.Base station in all residential quarters in cell cluster all is configured according to the above-mentioned uplink and downlink time slot configuration mode that has set each time slot for each frame.For example, base station B can pass through wireline interface (cable) or IP network etc., and the configuration information of the uplink and downlink time slot of bunch edge cell 2 is sent to base station A.In like manner, base station C can pass through wireline interface (cable) or IP network etc., distributes relevant information to send to base station A its resource.As example, each time slot TS0 '-TS6 ' in one frame of the configuration information indication bunch edge cell 2 of the uplink and downlink time slot of bunch edge cell 2 be respectively D D D U U D U, each the time slot TS0 in the frame of the configuration information indication bunch edge cell 3 of the uplink and downlink time slot of bunch edge cell 3 "-TS6 " be respectively D D U U D U U.

In the embodiment of a variation, preserve among the A of base station and in communication last time, to have obtained, the uplink and downlink configuration information of each time slot of one frame of bunch edge cell 2 and bunch edge cell 3, and up, the downstream arrangements of the time slot of bunch edge cell 2 and bunch edge cell 3 do not change till now from last time communicating by letter, and then base station A can utilize the configuration information of the uplink and downlink time slot of bunch edge cell 2 of preserving and bunch edge cell 3.

Then in step S11, according to the configuration information of uplink and downlink time slot, whether base station A determines at the configuration mode of the time slot corresponding with each time slot of buffer cells 1 of the first cell cluster CC1 and the second cell cluster CC2 consistent.Particularly, base station A determine time slot corresponding with each time slot of buffer cells 1 in bunch edge cell 2 and bunch edge cell 3 whether all by 2 configurations of bunch edge cell be used for uplink communication or all configuration for downlink communication, for example, for the time slot TS1 in the buffer cells 1, with it corresponding time slot TS1 ' and corresponding time slot TS1 with it in bunch edge cell 3 in bunch edge cell 2 " whether all be arranged to upstream or downstream and communicate by letter, also be ascending time slot or descending time slot.

In step S12, when base station A determines that the configuration mode of time slot corresponding with the one or more time slots in the buffer cells 1 in the first cell cluster CC1 and the second cell cluster CC2 is consistent, then base station A and configuration mode in the first cell cluster CC1 and the second cell cluster CC2 consistently will this one or more time slot configuration the upstream or downstream time slot that is buffer cells 1 so that interference between not producing between buffer cells 1 and the first cell cluster CC1, the second cell cluster CC2 bunch.

Particularly, base station A determine bunch edge cell 2 with time slot TS0 and TS1 respectively corresponding time slot TS0 ' and TS1 ' be configured to descending time slot (D), and bunch edge cell 3 will be distinguished corresponding time slot TS0 with time slot TS0 and TS1 " and TS1 " also be configured to descending time slot (D); Base station A determines that bunch edge cell 2 is configured to ascending time slot (U) with TS3 ' and the TS6 ' corresponding with time slot TS3 and TS6 difference, and base station A determine bunch edge cell 3 will with time slot TS3 and TS6 corresponding TS3 respectively " and TS6 " also be configured to ascending time slot (U), therefore, correspondingly, base station A is with TS0, TS1 also is configured to descending time slot, and TS3 and TS6 also are configured to ascending time slot.Like this, on time slot TS0 and TS1, bunch edge cell 2 and bunch edge cell 3 are descending time slot at above-mentioned time slot, so that do not disturb between can not producing between buffer cells 1 and bunch edge cell 2 and bunch edge cell 3 bunch; On time slot TS3 and TS6, bunch edge cell 2 and bunch edge cell 3 are ascending time slot at above-mentioned time slot, so that do not disturb between can not producing between buffer cells 1 and bunch edge cell 2 and bunch edge cell 3 bunch.And 3 pairs of bunch edge cell 2 and bunch edge cell are inconsistent with the configuration scenario that time slot TS2, TS4 and TS5 distinguish corresponding time slot, therefore, base station A is with the time slot TS2 of buffer cells 1, TS4 and TS5 are assigned as reservation, do not distribute to any portable terminal, therefore, at these time slots, do not disturb between can not producing because the uplink and downlink time slot configuration of these time slots is inconsistent between buffer cells 1 and bunch edge cell 2 and bunch edge cell 3 bunch yet.

The second embodiment

Fig. 4 has shown the method flow diagram that is used to buffer cells 1 configuration uplink and downlink time slot among the base station A according to another embodiment of the invention.Wherein, the resource that the second embodiment obtains for base station A distributes relevant information to comprise that the situation that is used to indicate interference-related information describes, because consider interference-related information, as shown in Figure 2, because bunch edge cell 2 adjacent with buffer cells 1 and bunch edge cell 3 can and buffer cells 1 between have potential interference, therefore, we describe as an example of bunch edge cell 2 and bunch edge cell 3 example below.

Referring to Fig. 4 and in conjunction with Fig. 1 and Fig. 2 a specific embodiment of the present invention is described.

In step S10 ', base station A obtains bunch edge cell 2 and resource corresponding to bunch edge cell 3 difference distributed relevant information, and wherein, resource distributes relevant information to comprise interference-related information.Wherein, interference-related information comprise in the following each or appoint multinomial:

I) be used to indicate on the time slot corresponding with each time slot of buffer cells 1 of bunch edge cell 2, whether produce the information disturbed between potential bunch and bunch edge cell 3 between bunch edge cell 2 and the buffer cells 1 with the corresponding time slot of each time slot of buffer cells 1 on, whether produce the information of disturbing between potential bunch between bunch edge cell 3 and the buffer cells 1, for example, the time slot corresponding with the time slot TS2 of buffer cells 1 of bunch edge cell 2 comprises: on time shaft with at least part of overlapping bunch edge cell 2 of TS2 time slot in time slot, such as TS2 ', because in the present embodiment, the time slot of each frame in buffer cells 1 and bunch edge cell 2 and bunch edge cell 3 is complete matching, therefore the time slot corresponding with the time slot TS0-TS6 of buffer cells is respectively TS0 '-TS6 ' in bunch edge cell 2, and time slot corresponding with the time slot TS0-TS6 of buffer cells in bunch edge cell 3 is respectively TS0 "-TS6 ".

The situation of disturbing between wherein can producing potential bunch between bunch edge cell and the buffer cells 1 comprise this bunch edge cell will with the corresponding time slot allocation of one or more time slots of buffer cells 1 to portable terminal, and this portable terminal is positioned at the cell edge of bunch edge cell, if what this portable terminal used is ascending time slot, then the uplink communication of this portable terminal can cause interference to the portable terminal that the corresponding time slot of the use in buffer cells 1 carries out downlink communication; If what this portable terminal used is descending time slot, then the downlink communication of this portable terminal corresponding time slot of use that can be subject in buffer cells 1 carries out the interference of the portable terminal of uplink communication.

Correspondingly, can not produce the situation of disturbing between potential bunch between bunch edge cell and the buffer cells 1 comprises: bunch edge cell not with bunch edge cell with the corresponding time slot allocation of one or more time slots of buffer cells 1 to portable terminal; Perhaps, it is inner to distribute the portable terminal of this time slot to be positioned at the residential quarter of bunch edge cell, far away apart from buffer cells 1.

Ii) whether be used to indicate bunch edge cell 2 and bunch edge cell 3 with the information of the time slot allocation corresponding with each time slot of buffer cells 1 in bunch edge cell to portable terminal, when this information indication time slot corresponding with one or more time slots of buffer cells 1 is not yet assigned to portable terminal, then base station A can determine on these one or more time slots, can not produce between this bunch edge cell and the buffer cells 1 between potential bunch to disturb.

Iii) be used to indicate the positional information of the portable terminal that on the time slot corresponding with one or more time slots of buffer cells 1, distributes of corresponding bunch of edge cell, when the indication of this information uses the portable terminal of bunch edge cell of the corresponding time slot of one or more time slots of buffer cells 1 to be positioned at the potential interference zone, when if this portable terminal is positioned at the potential interference zone, what use such as this portable terminal is ascending time slot, and then the uplink communication of this portable terminal can cause interference to the portable terminal that the corresponding time slot of the use in buffer cells 1 carries out downlink communication; If what this portable terminal used is descending time slot, then the downlink communication of this portable terminal corresponding time slot of use that can be subject in buffer cells 1 carries out the interference of the portable terminal of uplink communication, then base station A can determine on these one or more time slots, disturbs between meeting produces potential bunch between this bunch edge cell and the buffer cells.

In addition, when in considering bunch edge cell, having the situation of relay station, portable terminal at the edge of bunch edge cell can communicate by relay station and base station, therefore do not need to use very large transmitting power, although this moment, this portable terminal was in the edge of bunch edge cell, the upward signal of this portable terminal disturbs between can't producing potential bunch to buffer cells 1.Therefore, when having the situation of relay station, the position in the potential interference zone of the division of the position in the potential interference zone in the location dependent information when not having relay station divide may exist different.Therefore, when having relay station, the position of the portable terminal that disturbs between can producing potential bunch in bunch edge cell and between the buffer cells 1 is defined as the potential interference zone.

Interference-related information not only is confined to above-mentioned several settling the standard, and persons skilled in the art should be able to be according to the situation of real network, determine in bunch edge cell portable terminal whether can and buffer cells produce other situations of disturbing between potential bunch.

Particularly, base station B can pass through wireline interface (cable) or IP network etc., and interference-related information is sent to base station A.In like manner, base station C can pass through wireline interface (cable) or IP network etc., and interference-related information is sent to base station A.The send mode of other interference-related information also is feasible, and all should be within the protection range of the present invention and claim thereof.

In step S11 ', base station A whether determine according to the interference-related information obtained on the time slot corresponding with each time slot of buffer cells 1 of bunch edge cell 2 and bunch edge cell 3 can and buffer cells 1 between disturb between producing potential bunch or produce and disturb the corresponding time to support between potential bunch a kind of configuration mode is only arranged.

Particularly, when interfere information that base station A obtains in step S10 ' is to be used to indicate on the corresponding time slot of each time slot of buffer cells 1, whether produce the information that whether produces interference between potential bunch between the information disturbed between potential bunch and bunch edge cell 3 and the buffer cells 1 between bunch edge cell 2 and the buffer cells 1, then according to the indication of this interfere information, base station A can determine bunch edge cell 2 and bunch edge cell 3 the time slot corresponding with each time slot of buffer cells 1 whether can and buffer cells between disturb between producing potential bunch.

For example, interference-related information from bunch edge cell 2 is indicated on time slot TS0 ', TS4 ' and TS5 ', bunch edge cell 2 can and buffer cells 1 between disturb between producing potential bunch, and time slot TS0 ' is configured to descending time slot, time slot TS4 ' is configured to ascending time slot, and time slot TS5 ' is configured to descending time slot; From the indication of the interference-related information of bunch edge cell 3 at time slot TS0 " and TS4 " and TS6 " on; bunch edge cell 3 can and buffer cells 1 between disturb between producing potential bunch; and time slot TS0 " be configured to descending time slot, time slot TS4 " be configured to descending time slot, time slot TS6 " be configured to ascending time slot.

When determining bunch edge cell 2 and bunch edge cell 3, base station A do not producing interference between potential bunch on the time slot corresponding with one or more time slots of buffer cells 1 and between the buffer cells 1, or produce when disturbing corresponding time slot that a kind of uplink and downlink time slot configuration mode is only arranged between potential bunch, then in step S12 ', base station A correspondingly is configured to these one or more time slots of buffer cells 1 the upstream or downstream time slot of buffer cells 1.

For all not producing the one or more time slots that disturb between potential bunch between bunch edge cell 2 and bunch edge cell 3 and the buffer cells 1, comprise TS1, TS2 and TS3, base station A can be ascending time slot or descending time slot with above-mentioned time slot configuration.Preferably, if consistent in the uplink and downlink time slot configuration situation of bunch edge cell 2 and bunch edge cell 3 for a time slot, when being all ascending time slot or being all descending time slot, then in step S12 ', base station A is the uplink and downlink time slot configuration mode consistent with bunch edge cell 2 and bunch edge cell 3 with this time slot configuration, also is ascending time slot or descending time slot.For example for TS1, base station A also is configured as descending time slot; And for a time slot, when its uplink and downlink time slot configuration situation in bunch edge cell 2 and bunch edge cell 3 was inconsistent, base station A can be the upstream or downstream time slot with this time slot configuration according to certain strategy, for example TS2 was configured to the upstream or downstream time slot.Wherein certain strategy comprises random arrangement or considers that the uplink and downlink configuration of buffer cells 1 is balanced, and this will be understood that for those skilled in the art, does not therefore repeat them here.

To there being one or more time slots of potential interference, each time slot among TS0, TS4, TS5 and the TS6 for example, by configuration compares to the uplink and downlink of the corresponding time slot of the time slot with buffer cells 1 of each adjacent bunch edge cell, disturb between judging whether to produce bunch.

Particularly, for time slot TS0, TS0 ' in bunch edge cell 2 is descending time slot, and on TS0 ', bunch edge cell 2 can and buffer cells 1 between disturb between producing potential bunch, TS0 in bunch edge cell 3 " also be descending time slot; and at TS0 " on, bunch edge cell 3 can and buffer cells 1 between disturb between producing potential bunch, because can produce between potential bunch the upper of bunch edge cell 2 disturbed and 3, the descending time slot configuration mode only has a kind of, be all descending time slot, therefore, base station A with the time slot TS0 of buffer cells 1 also be configured to in consistent upper of the type of bunch edge cell 2 and bunch edge cell 3, the descending time slot configuration mode also, also is configured to descending time slot.

For time slot TS4, because time slot TS4 ' is configured to ascending time slot in bunch edge cell 2, and between can producing potential bunch on this ascending time slot and between the buffer cells 1, disturb, time slot TS4 in bunch edge cell 3 " be configured to descending time slot; and at this time slot TS4 " on, disturb between can producing potential bunch between bunch edge cell 3 and the buffer cells 1.Because in bunch edge cell 2 and bunch edge cell 3, different from the uplink and downlink time slot configuration mode of the corresponding time slot of time slot TS4, so base station A is made as reservation (Reserved) with this time slot TS4, also namely regardless of being used in upstream or downstream communication.

For time slot TS5, although bunch edge cell 2 and bunch edge cell 3 are upper for the corresponding time slot of time slot TS5, the descending time slot configuration mode is inconsistent, but only have on the descending time slot TS5 ' corresponding with time slot TS5 in bunch edge cell 2, bunch edge cell 2 can and buffer cells 1 between disturb between producing potential bunch, and the ascending time slot TS5 corresponding with time slot TS5 in bunch edge cell 3 " on; bunch edge cell 3 not can and buffer cells 1 between disturb between producing potential bunch; therefore, base station A time slot TS5 is configured to and buffer cells 1 between bunch edge cell 2 disturbed between can producing potential bunch adopt upper; the descending time slot that the descending time slot configuration mode is consistent;

For time slot TS6, only have on the ascending time slot TS6 ' corresponding with TS6 in bunch edge cell 3, bunch edge cell 3 can and buffer cells 1 between disturb between producing potential bunch, and the corresponding ascending time slot TS6 of the TS6 in bunch edge cell 2 " on; bunch edge cell 2 not can and buffer cells 1 between disturb between producing potential bunch; therefore; what bunch edge cell 3 of interference adopted between base station A was configured to time slot TS6 to produce potential bunch between participant and the buffer cells 1 is upper; consistent upper of descending time slot configuration mode; the descending time slot configuration mode, also namely, base station A is configured to ascending time slot with TS6.

In the embodiment of a variation, buffer cells 1 is adjacent with a plurality of bunches of edge cell of at least two cell clusters, for example, buffer cells is adjacent with bunch edge cell 2 and 4 that belongs to a cell cluster, adjacent with bunch edge cell 3 and 5 that belongs to another cell cluster, very the person also with another cell cluster in the adjacent (not shown) of bunch edge cell.In same cell cluster, the uplink and downlink time slot configuration mode of all residential quarters all is consistent, be all to be configured to ascending time slot in the different districts of same time slot in same cell cluster or all to be configured to descending time slot, but, for a concrete time slot, the disturbed condition of the different districts in the same cell cluster may not be consistent.For example, for time slot TS0, bunch edge cell 2 in same cell cluster is on the corresponding descending time slot TS0 ' of time slot TS0, bunch edge cell 2 can and buffer cells 1 between disturb between producing potential bunch, and bunch edge cell 4 is on the corresponding descending time slot of time slot TS0, bunch edge cell 4 not can and buffer cells 1 between disturb between producing potential bunch.Therefore, bunch edge cell 2 of interference between base station A only need consider to produce potential bunch between meeting and the buffer cells 1.In addition, if can and buffer cells 1 between bunch edge cell disturbed between producing potential bunch uses is same uplink and downlink time slot configuration mode, namely be all ascending time slot or be all descending time slot, the consistent time slot of residential quarter uplink and downlink time slot configuration mode that base station A just can disturb between being configured to produce potential bunch between participant and the buffer cells 1 for buffer cells 1.

In the embodiment of another variation, the interfere information that obtains in step S10 ' as base station A is to be used to indicate time slot allocation that whether bunch edge cell 2 and bunch edge cell 3 will be corresponding with one or more time slots of buffer cells 1 to the information of portable terminal, for example, the information exchange that base station B is not yet assigned to portable terminal with time slot TS3 ' is crossed wireline interface (cable) or IP network etc. and is sent to base station A, then in step S11 ', base station A according to bunch edge cell 2 will be not corresponding with time slot TS3 time slot TS3 ' distribute to the information of portable terminal, determine on this time slot TS3, bunch edge cell 2 not can and buffer cells 1 between disturb between producing potential bunch.

In the embodiment of another variation, referring to Fig. 2, the interfere information that base station A obtains in step S10 ' is the positional information that is used to indicate the portable terminal that bunch edge cell 2 and bunch edge cell 3 distribute at the time slot corresponding with one or more time slots of buffer cells 1.For example, base station B distributes to portable terminal with time slot TS4 ' when this positional information indication, and the zone that this portable terminal disturbs produce potential bunch between the meeting of bunch edge cell 2 and buffer cells 1 between the time, base station B sends to base station A by wireline interface (cable) or IP network etc. with this location dependent information, then in step S11 ', base station A is according to the location dependent information of the portable terminal that distributes time slot TS4 ', and definite time slot TS4 corresponding with time slot TS4 ' disturbs between putting on an arrow and producing potential bunch between edge cell 2 meetings and the buffer cells 1.

The 3rd embodiment

The 3rd embodiment is combination preferred embodiment a kind of of the first embodiment and the second embodiment.

Describe with reference to Fig. 2,3 and 4.At first, base station A obtains bunch edge cell 2 and resource corresponding to bunch edge cell 3 difference distributed relevant information, wherein resource distributes relevant information to comprise configuration information and the interference-related information of uplink and downlink time slot, wherein, configuration information and interfere information are respectively as described in above-mentioned the first embodiment and the second embodiment.

Then base station A is according to upper, the configuration information of descending time slot, step S10 and step S11 according to the first embodiment operate, in step S12, when base station A determines that the configuration mode of the time slot corresponding with one or more time slots of buffer cells 1 of the first cell cluster CC1 and the second cell cluster CC2 is consistent, then base station A and configuration mode in the first cell cluster CC1 and the second cell cluster CC2 consistently will these one or more time slot configuration the upstream or downstream time slot that is buffer cells 1 so that buffer cells 1 and the first cell cluster CC1, do not disturb between not producing between the second cell cluster CC2 bunch.

When base station A determines that the configuration mode of the time slot that the first cell cluster CC1 is corresponding with the one or more time slots with in the buffer cells 1 among the second cell cluster CC2 is inconsistent, then base station A is further according to interfere information, utilize the step among the second embodiment to be further processed to the inconsistent time slot of uplink and downlink configuration mode in bunch edge cell 2 and bunch edge cell 3, those skilled in the art will be understood that and not repeat them here.

In the embodiment of a variation, even on the time slot corresponding with time slot TS4, when bunch edge cell 2 and bunch edge cell 3 all can and buffer cells 1 between disturb between producing potential bunch, and set upper of bunch edge cell 2 and bunch edge cell 3, when the configuration mode of descending time slot is inconsistent, for example bunch edge cell 2 time slot TS4 ' that TS4 is corresponding is set to ascending time slot, bunch edge cell 3 time slot TS4 that TS4 is corresponding " be set to descending time slot; base station A still can distribute to this time slot TS4 and be in portable terminal in the non-potential interference zone as ascending time slot in buffer cells 1; because the portable terminal that distributes is positioned at non-potential interference zone; therefore; the uplink communication of this portable terminal can not disturb bunch edge little 3 with time slot TS4 " carry out the portable terminal of downlink communication, and the portable terminal in the buffer cells 1 carries out uplink communication at time slot TS4, portable terminals in bunch edge cell 2 also adopt uplink communication at time slot TS4 ', so interference between also can not producing between buffer cells 1 and bunch edge cell 2 bunch.

In the embodiment of a variation, the buffer area comprises a plurality of other buffer cells, and the configuration mode of the uplink and downlink time slot between a plurality of buffer cells in the buffer area can be incomplete same.Therefore, after the configuration mode of the uplink and downlink time slot of buffer cells 1 was determined, base station A can be with the configuration relevant information of its uplink and downlink time slot and/or other buffer cells of interference-related information notice buffer area.

Correspondingly, after other buffer cells adjacent with buffer cells 1 receive configuration relevant information and/or interference-related information from the uplink and downlink time slot of buffer cells 1, other buffer cells are also seen buffer cells 1 as a bunch of edge cell, and be these other buffer cells collocating uplink or descending time slots according to the aforesaid method of this specification, do not repeat them here.

More than for the time slot of the first cell cluster CC1 and the second cell cluster CC2 and the situation of buffer cells 1 complete matching are specifically described, when the first cell cluster CC1, the second cell cluster CC2 not exclusively alignd with the time slot of buffer cells 1 or be not exclusively synchronous, above-described technical scheme was also fully applicable.

Particularly, Fig. 5 is the schematic diagram according to the uplink and downlink time slot configuration of bunch edge cell 2 of another specific embodiment of the present invention and bunch edge cell 3.Wherein, each time slot in each time slot in the frame of bunch edge cell 2 and the frame of buffer cells 1 does not have complete matching, and each time slot in the frame of bunch edge cell 3 and buffer cells 1 a frame in each time slot align.Bunch edge cell that each and buffer cells 1 are adjacent and the time slot of buffer cells 1 can all not line up, and perhaps wherein one or more adjacent bunch edge cell are alignd with buffer cells 1.

Base station A has obtained the relevant information of the frame format separately of bunch edge cell 2 and bunch edge cell 3, wherein, comprises zero-time and the termination time of each time slot in bunch edge cell 2 and bunch edge cell 3 frame separately.Therefore, base station A can be according to zero-time and the termination time of each time slot in the frame of bunch edge cell 2 and bunch edge cell 3, judge the corresponding relation between each time slot of itself and buffer cells 1, wherein, at least part of overlapping time slot is corresponding time slot on the time.

Take TS1 as example, the time slot corresponding with the time slot TS1 of buffer cells 1 in bunch edge cell 2 is TS0 ' and TS1 ', and the time slot corresponding with the time slot TS1 of buffer cells 1 in bunch edge cell 3 is TS1 ".

Then for the first embodiment changes in the example, in step S11 ', base station A determines that bunch edge cell 2 all is configured to descending time slot with time slot TS0 ', the TS1 ' corresponding with the time slot TS0 of buffer cells 1, and bunch edge cell 3 will with the corresponding time slot TS0 of the time slot TS0 of buffer cells 1 " be configured to descending time slot.Therefore, correspondingly, in step S12 ', base station A also is configured to descending time slot with the time slot TS0 in the buffer cells 1.Like this, on time slot TS0, buffer cells 1, bunch edge cell 2 and 3 are descending time slot at above-mentioned time slot, so that do not disturb between can not producing between buffer cells 1 and bunch edge cell 2 and bunch edge cell 3 bunch.

Still with reference to Fig. 5, of the second embodiment of the present invention is changed example, and to carry out brief description as follows:

In step S10 ', the interference-related information that base station A obtains comprises: on the time slot TS3 ' corresponding with time slot TS4 of bunch edge cell 2, bunch edge cell 2 can and buffer cells 1 between disturb between producing potential bunch, the time slot TS4 corresponding with time slot TS4 of bunch edge cell 3 " on, bunch edge cell 3 can and buffer cells 1 between disturb between producing potential bunch.

Therefore, in step S11 ', base station A determines: for time slot TS4, time slot TS2 ' corresponding with time slot TS4 in bunch edge cell 2 is configured to ascending time slot, and on time slot TS2 ', bunch edge cell 2 not can and buffer cells 1 between disturb between producing potential bunch, time slot TS3 ' corresponding with time slot TS4 in bunch edge cell 2 is configured to descending time slot, and on time slot TS3 ', bunch edge cell 2 can and buffer cells 1 between disturb between producing potential bunch, the time slot TS4 corresponding with time slot TS4 in bunch edge cell 3 " be configured to descending time slot; and at this time slot TS4 " on, disturb between can producing potential bunch between bunch edge cell 3 and the buffer cells 1.

Because in bunch edge cell 2 and bunch edge cell 3, time slot TS3 ' and TS4 that can be corresponding with the TS4 that disturbs between producing potential bunch between the buffer cells 1 " all be configured to descending time slot; and so base station A is in step S12 '; the consistent uplink and downlink time slot configuration of uplink and downlink time slot configuration mode of interference between time slot TS4 is configured to produce potential bunch between participant and the buffer cells 1; also namely, base station A is configured to descending time slot with TS4.

In some cases, in the situations such as the uplink and downlink service distribution changes, bunch edge cell 2 and/or bunch edge cell 3 can dynamically change its uplink and downlink timeslot configuration, and generate new resource distribution relevant information.At this moment, the base station A of buffer cells 1 will repeat above step, and namely the resource of the renewal of basis bunch edge cell 2 and/or bunch edge cell 3 is distributed relevant information, redefine the time slot configuration scheme of this buffer cells.

More than be angle from the base station A of buffer cells 1 present invention is described, below will present invention is described from the angle of the base station of the cell cluster adjacent with buffer cells 1.

Fig. 6 shows the method flow diagram that is used for the base station A configuration uplink and downlink time slot of auxiliary buffer cells 1 in the base station of the cell cluster adjacent with buffer cells 1 of cordless communication network according to a second aspect of the invention.

In step S20, to belonging to the cell cluster adjacent with buffer cells 1, take the first cell cluster CC1 as example, base station D in the non-bunch of edge cell 6 among the first cell cluster CC1 according to be used to indicate among the first cell cluster CC1 bunch edge cell adjacent with buffer cells 1 whether time slot allocation that one or more time slots of bunch edge cell are corresponding to the information of portable terminal and/or the positional information that is used to indicate the portable terminal of the corresponding time slot of one or more time slots of being assigned buffer cells 1 in bunch edge cell generate interference-related information, wherein, interference-related information is used to indicate on the time slot corresponding with one or more time slots of buffer cells 1, whether can produce the information of disturbing between potential bunch between bunch edge cell and the buffer cells 1.Below describe as bunch edge cell 2 as example take bunch edge cell adjacent with buffer cells 1.Base station D can communicate with base station B by wireline interface (cable) or IP network etc.Though above base station D in the non-bunch of edge cell 6 describe as example, those skilled in the art will be understood that above-mentioned steps is also applicable to bunch edge cell in the cell cluster.

In the embodiment of a variation, referring to Fig. 2, when the information that base station D obtains is the positional information that is used to indicate the portable terminal that distributes on the time slot corresponding with one or more time slots of buffer cells 1 in bunch edge cell 2.For example, this positional information indication base station B distributes to portable terminal with time slot TS4 ', and this portable terminal the edge of bunch edge cell 2 can and buffer cells 1 between disturb between producing potential bunch regional the time, then base station D generates interference-related information, be included in upper this bunch edge cell 2 of the time slot TS4 ' corresponding with time slot TS4 can and buffer cells 1 between disturb between producing potential bunch.

In step S21, base station D sends the resource of the first cell cluster CC1 at D place, base station and distributes relevant information to base station A, and wherein, resource distribution relevant information comprises the interference-related information between bunch edge cell 1 and the buffer cells 1.

Base station D can be in the uplink and downlink time slot configuration information of each time slot of pre-set each frame of base station B, and after each time slot being pre-assigned to or determining to be not yet assigned to portable terminal, interference-related information is sent to base station A.

In the embodiment of a variation, step S20 can omit, and then in step S21, base station D directly sends the resource distribution relevant information of bunch edge cell 2 to base station A, wherein, resource distribution relevant information comprises the interference-related information between bunch edge cell 2 and the buffer cells 1.Wherein, interference-related information comprise following each or appoint multinomial:

-be used to indicate among the first cell cluster CC1 bunch edge cell adjacent with buffer cells 12 whether will with the information of the corresponding time slot allocation of one or more time slots of buffer cells 1 to portable terminal;

-be used to indicate the positional information of the portable terminal that bunch edge cell 2 of the first cell cluster CC1 distributes on the time slot corresponding with one or more time slots of buffer cells 1.

In the embodiment of another variation, in step S21, base station D distributes relevant information to the resource that base station A sends bunch edge cell 2, and wherein, resource distributes relevant information to comprise uplink and downlink time slot configuration information.

In the embodiment of another variation, in step S21, base station D distributes relevant information to the resource that base station A sends bunch edge cell 2, and wherein, resource distributes relevant information to comprise uplink and downlink time slot configuration information and interference-related information.

In some cases, in the situations such as the uplink and downlink service distribution changes, base station B can dynamically change its uplink and downlink time slot configuration.At this moment, base station D will repeat above step, distribute relevant information to offer base station A new resource.

The above-mentioned steps S20 that base station D finishes and S21 can be finished by the base station of any one residential quarter in the first cell cluster CC1 fully, as long as can intercom mutually between the base station in the first cell cluster CC1.When above-mentioned steps was performed by the base station of bunch edge cell 2, in step S20, the resource that base station B can directly obtain this base station distributed relevant information to operate.

Determine that device 1010 ' determines on the corresponding time slot of bunch edge cell 2 and one or more time slots of bunch edge cell 3 in buffer cells 1 and do not produce between the buffer cells 1 between potential bunch to disturb when the 3rd, or produce when disturbing corresponding time slot that a kind of uplink and downlink time slot configuration mode is only arranged between potential bunch, then the 3rd inking device 1011 ' correspondingly is configured to these one or more time slots of buffer cells 1 the upstream or downstream time slot of buffer cells 1.

For all not producing the one or more time slots that disturb between potential bunch between bunch edge cell 2 and bunch edge cell 3 and the buffer cells 1, comprise TS1, TS2 and TS3, the 3rd inking device 1011 ' can be ascending time slot or descending time slot with above-mentioned time slot configuration.Preferably, if consistent in the uplink and downlink time slot configuration situation of bunch edge cell 2 and bunch edge cell 3 for a time slot, when being all ascending time slot or being all descending time slot, then the 3rd inking device 1011 ' is the uplink and downlink time slot configuration mode consistent with bunch edge cell 2 and bunch edge cell 3 with this time slot configuration, also is ascending time slot or descending time slot.For example for TS1, the 3rd inking device 1011 ' also is configured as descending time slot; And for a time slot, when its uplink and downlink time slot configuration situation in bunch edge cell 2 and bunch edge cell 3 is inconsistent, the 3rd inking device 1011 ' can be the upstream or downstream time slot with this time slot configuration according to certain strategy, for example TS2 is configured to the upstream or downstream time slot.Wherein certain strategy comprises random arrangement or considers that the uplink and downlink configuration of buffer cells 1 is balanced, and this will be understood that for those skilled in the art so does not repeat them here.

Particularly, for time slot TS0, TS0 ' in bunch edge cell 2 is descending time slot, and on TS0 ', bunch edge cell 2 can and buffer cells 1 between disturb between producing potential bunch, TS0 in bunch edge cell 3 " also be descending time slot; and at TS0 " on, bunch edge cell 3 can and buffer cells 1 between disturb between producing potential bunch, because bunch edge cell 2 that the 3rd definite device 1010 ' disturbs between determining to produce potential bunch and 3 is upper, the descending time slot configuration mode only has a kind of, be all descending time slot, therefore, the 3rd inking device 1011 ' with the time slot TS0 of buffer cells 1 also be configured to in consistent upper of the type of bunch edge cell 2 and bunch edge cell 3, the descending time slot configuration mode also, also is configured to descending time slot.

For time slot TS4, because time slot TS4 ' is configured to ascending time slot in bunch edge cell 2, and between can producing potential bunch on this ascending time slot and between the buffer cells 1, disturb, time slot TS4 in bunch edge cell 3 " be configured to descending time slot; and at this time slot TS4 " on, disturb between can producing potential bunch between bunch edge cell 3 and the buffer cells 1.Because the 3rd definite device 1010 ' is determined in bunch edge cell 2 and bunch edge cell 3, different from the uplink and downlink time slot configuration mode of the corresponding time slot of time slot TS4, TS4 ' is ascending time slot in bunch edge cell 2, and TS4 " be descending time slot in bunch edge cell 3; therefore the 3rd inking device 1011 ' is made as reservation (Reserved) with this time slot TS4 in buffer cells 1, also namely does upstream or downstream communication regardless of being used in.

For time slot TS5, although the 3rd determines that device 1010 ' determines upper for the corresponding time slot of time slot TS5 of bunch edge cell 2 and bunch edge cell 3, the descending time slot configuration mode is inconsistent, but only have on the descending time slot TS5 ' corresponding with time slot TS5 in bunch edge cell 2, bunch edge cell 2 can and buffer cells 1 between disturb between producing potential bunch, and the ascending time slot TS5 corresponding with time slot TS5 in bunch edge cell 3 " on; bunch edge cell 3 not can and buffer cells 1 between disturb between producing potential bunch; therefore, the 3rd inking device 1011 ' time slot TS5 is configured to and buffer cells 1 between bunch edge cell 2 disturbed between can producing potential bunch adopt upper; the descending time slot that the descending time slot configuration mode is consistent;

For time slot TS6, the 3rd determines on device 1010 ' definite ascending time slot TS6 ' corresponding with TS6 that only has in bunch edge cell 3, bunch edge cell 3 can and buffer cells 1 between disturb between producing potential bunch, and the corresponding ascending time slot TS6 of the TS6 in bunch edge cell 2 " on; bunch edge cell 2 not can and buffer cells 1 between disturb between producing potential bunch; therefore; what bunch edge cell 3 of interference adopted between the 3rd inking device 1011 ' was configured to time slot TS6 to produce potential bunch between participant and the buffer cells 1 is upper; consistent upper of descending time slot configuration mode; the descending time slot configuration mode, also namely, base station A is configured to ascending time slot with TS6.

In the embodiment of a variation, buffer cells 1 is adjacent with a plurality of bunches of edge cell of at least two cell clusters, for example, buffer cells is adjacent with bunch edge cell 2 and 4 that belongs to a cell cluster, adjacent with bunch edge cell 3 and 5 that belongs to another cell cluster, very the person also with another cell cluster in the adjacent (not shown) of bunch edge cell.In same cell cluster, the uplink and downlink time slot configuration mode of all residential quarters all is consistent, be all to be configured to ascending time slot in the different districts of same time slot in same cell cluster or all to be configured to descending time slot, but, for a concrete time slot, the disturbed condition of the different districts in the same cell cluster may not be consistent.For example, for time slot TS0, bunch edge cell 2 in same cell cluster is on the corresponding descending time slot TS0 ' of time slot TS0, bunch edge cell 2 can and buffer cells 1 between disturb between producing potential bunch, and bunch edge cell 4 is on the corresponding descending time slot of time slot TS0, bunch edge cell 4 not can and buffer cells 1 between disturb between producing potential bunch.Therefore, the 3rd determine device 1010 ' only need to consider can and buffer cells 1 between bunch edge cell 2 disturbed between producing potential bunch.In addition, if can and buffer cells 1 between bunch edge cell disturbed between producing potential bunch uses is same uplink and downlink time slot configuration mode, namely be all ascending time slot or be all descending time slot, the consistent time slot of residential quarter uplink and downlink time slot configuration mode that the 3rd inking device 1011 ' just can disturb between being configured to produce potential bunch between participant and the buffer cells 1 for buffer cells 1.

In the embodiment of another variation, the interfere information that obtains in deriving means 100 ' is to be used to indicate time slot allocation that whether bunch edge cell 2 and bunch edge cell 3 will be corresponding with one or more time slots of buffer cells 1 to the information of portable terminal, for example, the information exchange that base station B is not yet assigned to portable terminal with time slot TS3 ' is crossed wireline interface (cable) or IP network etc. and is sent to base station A, then the 3rd determines that device 1010 ' will corresponding time slot TS3 ' with time slot TS3 do not distribute to the information of portable terminal according to bunch edge cell 2, determine on this time slot TS3, bunch edge cell 2 not can and buffer cells 1 between disturb between producing potential bunch.

In the embodiment of another variation, referring to Fig. 2, the interfere information that deriving means 100 ' obtains is to be used to indicate the positional information that bunch edge cell 2 and bunch edge cell 3 are the portable terminal that distributes on the corresponding time slot of one or more time slots of buffer cells 1.For example, base station B distributes to portable terminal with time slot TS4 ' when this positional information indication, and during the location dependent information in the zone that this portable terminal disturbs produce potential bunch between the meeting of bunch edge cell 2 and buffer cells 1 between, base station B sends to deriving means 100 ' by wireline interface (cable) or IP network etc., then the 3rd definite device 1010 ' is distributed to the location dependent information of portable terminal according to time slot TS4, for example, determine the corresponding time slot TS4 of TS4 ' put on an arrow edge cell 2 can and buffer cells 1 between disturb between producing potential bunch.
